First things first: Lisa's jewelry is beautiful. Flat out, it's gorgeous. It's that perfect mix of modern and vintage that I get completely geeky over. You'll have a harder time finding something you don't want in the shop than something you do.
That's not enough for you? Oh, FINE! You can also check out her awesome blog, the most recent entry on which is about the wonders of social media for advertising. Great tips and tricks, especially for those who are new to networking with fellow Etsians and potential buyers via things like Twitter.
She also puts together beautiful selections of "Etsy picks" to show off the work of other artists. But, honestly, even if she never said a word or Tweeted a single thing, the work is beautiful. Take a moment to visit her shop, fan her on Facebook, and enjoy the view!
